We varied (a) the acceleration and frequency of shaking, and (b) the liquid viscosity. The experiments were conducted to understand the diversity and scaling relation of the phenomena associated with liquefaction. From the experiments we found that (i) a gravitational instability occurs as a consequence of accumulation of the liquid beneath the less permeable upper layer, (ii) there is a critical acceleration for the instability to occur, (iii) the critical acceleration decreases when the liquid has a higher viscosity. We formulated scaling laws to explain these results. Our results indicate that both shaking acceleration and velocity are important for liquefaction. Furthermore they show that when the liquid is more viscous, a granular medium can become more susceptible to liquefaction due to the enhanced interparticle lubrication.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号: 24510246, 研究期間(年度):2012-04-01 - 2016-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「液状化と流体移動：その多様性を実験と無次元数を用いて理解する」課題番号24510246\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-24510246/24510246seika/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域地球社会基盤学系","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00051901","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=90334747"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=90334747","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-24510246/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-24510246/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-24510246/24510246seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-24510246/24510246seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"隅田, 育郎"}],"nameIdentifiers":[{"nameIdentifier":"79102","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"90334747","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=90334747"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-08-16"}],"displaytype":"detail","filename":"SC-PR-SUMITA-I-kaken 2016-5p.pdf","filesize":[{"value":"616.3 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-SUMITA-I-kaken 2016-5p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/45564/files/SC-PR-SUMITA-I-kaken 2016-5p.pdf"},"version_id":"aa2d4911-2655-44d3-a87c-fa8567836c82"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"液状化と流体移動：その多様性を実験と無次元数を用いて理解する","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"液状化と流体移動：その多様性を実験と無次元数を用いて理解する"},{"subitem_title":"Understanding the diversity of Liquefaction and fluid transport using dimensionless numbers","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2818"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-08-16"},"publish_date":"2018-08-16","publish_status":"0","recid":"45564","relation_version_is_last":true,"title":["液状化と流体移動：その多様性を実験と無次元数を用いて理解する"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-07-01T05:44:47.744621+00:00"}
